## Uso de RLS
|
|
|
|
### Establecer Contexto de Tenant
|
|
|
|
```sql
|
|
-- En cada request
|
|
SELECT auth.set_current_tenant('tenant-uuid-here');
|
|
|
|
-- Opcional: establecer usuario
|
|
SELECT auth.set_current_user('user-uuid-here');
|
|
```
|
|
|
|
### Desde el Backend
|
|
|
|
```typescript
|
|
// Middleware de tenant
|
|
async function setTenantContext(tenantId: string) {
|
|
await dataSource.query('SELECT auth.set_current_tenant($1)', [tenantId]);
|
|
}
|
|
|
|
// En el request handler
|
|
const tenantId = req.user.tenantId;
|
|
await setTenantContext(tenantId);
|
|
// Ahora todas las queries respetan RLS
|
|
```
|
|
